| molecular evidence for a species complex in the patagonian lizard liolaemus bibronii and phylogeography of the closely related liolaemus gracilis (squamata: liolaemini). | the lizard genus liolaemus is endemic to temperate south america and includes 190 species. liolaemus bibronii has a large geographic distribution and inhabits a great diversity of habitats, including the monte, steppe, and high andean grassland environments. liolaemus gracilis has a similar body size and shape to l. bibronii; the two are parapatrically distributed, and l. gracilis is also widely distributed. here we use the mtdna cytb sequence data of these two species to investigate lizard phyl ... | 2007 | 17116410 |
